Monitoring Collection Listings

Hi all - I hope this is within the scope of what I can post here.

I have been trying and struggling to create a bot that can monitor NFT listings on Open sea.

Does anyone know how/ have an idea of how to make that happen?

I am hearing the Opensea APIs are hard to come by and am trying to skirt around that issue but am hitting a wall every time. Any advice or help would be much appreciated!
